Boric Acid

Abstract

With the advent of boric acid insecticides, accidental ingestion of the compound can be encountered in animals. Toxic levels of boric acid most commonly cause vomiting, depression, and, occasionally, diarrhea. Boric acid is, however, cytotoxic to all cells. If a sufficiently high level is ingested, seizures, renal tubular nephrosis, and, rarely, hepatotoxicity may be noted. Gastrointestinal evaluation and supportive care are usually of primary therapeutic importance, although in severe cases, exchange transfusion and/or peritoneal dialysis may be required to decrease blood boron concentrations.
